BALE-TYING ATTACHMENT.-

Nio. 875,654.

' Application filed September the art to which it pertains to make and use 'thesame, reference being had to. the accomyi g drawings, which form apart of this specification.

Thisinvention relates to a bale tying attachment to hay resses.

It has for its 0 jectan improved attachment adapted to be placed on any hay press of ordinary construction and is to be used for the purpose of securing together the ends of the bale wire by which the bale is bound.

In the drawing :-Figure 1, shows anelevationof the bale delivery chamber of a hay ress with the attachment secured. thereto.

ig. 2., is a reverse view of the attachment on an enlarged scale. Flg. 3, is a perspective of the twist wheel. Fig. 4, isa, perspective of the wire holding jaw; -Fig. 5,

shows two ends of wire twisted together. Fig. 6, shows twoends of wire looped together and twisted. Fig. 7 is a vertical sec-' tion through the center portion of Fig. 2,

. and at right angles to the plane of that Fig., showing the rack and pinion engagements are spaced along and the returning spring.

To one of the frame timbers 6 which. in-

close the delivery chamber of a hay press is secured a rod 1 which supports and guides a hanging frame 2.. The supports 3. and t of the rod are'brackets which hold the rod parallel to, but spaced from, the'timber 6. The frame 2 consists of two-parallel bars 7 and 8 secured at their upper end .to a head 9 that is provided with an eye to engage on the rod 1. At intervals below the head 9 are secured side brackets 10 and 11 which he bars to correspond with the location a lace the bale ties around the bale. These rackets are in pairs and are op osite to each other; journaled between eac pair of brackets on the frame bars 7 and 8 isa wheel 12 provided with gear teeth and with a notch 13 that extends into the wheel to and slightly beyond the center thereof and extends into the journal's which project at Specification of Letters Patent.

.each side from the face of the wheel. A

corresponding notch 14 is cut in each of the frame bars 7 and 8 leading into the notch 13 and the corresponding notches 15 and 16 are cut in the brackets 10 and 11. There is thus provided entirely across the frame and the brackets connected with it, a passage in which the ends of the tie wire may be laid with the central part of the overlap of the two ends of the wire lying substantially at the center of the wheel 12.

A rack 19 engages along the frame and is in position to actuate and rotate the several .wheels 12; the rack is held in place by yokes 20 which extend across from the side piece 10 to the side piece 11 at each pair of brackets, thus holding the rack securely in place and preventing it from springing away from engagement with either of the wheels with which it engages. The rack is provided with a foot-stirrup 22 by means of which it is forced downward and is retracted by means of a, spring 23 when the pressure of the foot is removed. 2 The stops 24 and 25 limit the throw of therack and cause-it to stop with the notches 13 in the roper osition. On the up-stroke, the notcii shoul stop exactly opposite the notch in'the frame iece on the down-stroke, the wheels sho d overthrow the notches in the frame by about the thickness of the wire and when the ressure of the foot is removed, the spring 0 the wire will bring the notch of the wheel to the proper place with respect to the notch in the frame to readily disengage the now twisted .wires from the attachment. the attachment near the head'9 .lsa'small pointed pin 27 which'engages in the hay of At the upper end of the bale and causes the attachment to travel with the bale during the progress of the halo through the delivery chamber.

In practice, the operator moves the attachment toward the receiving end of the delivery chamber (to the'left in the drawing) and drops it against a bale at a time when the bar is midway between two division boardsAand The wires with which the bale is to be bound are then passed along the grooves in the division boards to bring the two free ends of the wires to the near side of the bale; the ends of the wires are then crossed over the atjtachment and the now parallel lying ends of the wires are dro ped into thenotches in the ;frame and into the notch in the wheel. All of the wires of the several bale bands may be engaged in the attachment at the same time or only a single pair of overlapping ends as may be desired; after the ends of one or more of the bale bands have been caught in the notches, the workman pulls down the rack with his foot, releases the rack which is returned by the s ring, swings the lower end or hanging and 0 the attachment out from the press, releases the wires and carries the attachment back to its original location for Work on a new bale.

By the operation of the machine, the two ends of the wires have been given a double twist, and have been given two, three or four turns depending upon the position at which the downward pressure ceased. The bale band is perfectly secured, nosuperfluous wire has been necessary beyond that which is sulficient to pass once around the bale and lap at the ends just across from the bracket 10 to the bracket 11. The two wires may be linked together and twisted, as shown in Fig. 6, by loo ing the Wires together and bending each end arts interlinked and placing the thus interlinked wires in the twisting wheel and operating the twisting wheel as previously explained.

What I claim is 1. A bale fastening attachment for hay presses, having in combination a supporting,

' bracket, a hanger adapted't oslide therealong,

notched wire-receiving brackets at intervals along said hanger, rotatable wheels journaled opposite each of said brackets, each having a notched portion extending from its periphcry to the center adapted to register with the complementary art of its bracket, and means for simu taneously actuating said wheels, substantially as described.

back on itself with the two bent 2. A bale band fastening attachment for hay presses, having in combination a track, a hanger adapted to travel on said track, wire holding brackets secured to said hanger, a

-wire twisting-wheel journaled between said brackets,.the said wire twisting wheel being provided with a notch extending through a side thereof into said Wheel to the center thereof, and means for rotating said wheel, substantially as described.

3. A wire twisting attachment for hay presses, having in combination with a supporting trackway fixed members ada ted to travel therealong and to hold the apping registry of the indented portion With'one of v the notched-portions of the frame, and a rack 'slidably supported by said frame with its teeth in engagement with said gear Wheels, whereby the same may be actuated, substantially as described.

In testimony whereof, I sign this specification in the presence of two witnesses.
